s2014, establishing a driving model, namely establishing a mapping relation between the scene elements and the independent variables; that is, the driving model corresponds to a mapping model between the uterine contraction data and the feedback signal;
preferably, the step S2014 includes:
s20141, establishing an animation playing speed model, wherein the model is used for calculating the required playing speed of the model animation when the uterus contracts according to the normal playing speed of the model animation, the instantaneous slope of the uterus contraction curve and the uterus pressure value;
specifically, in the scene playing process, along with the increase of pain of the pregnant woman, namely the ascending period of uterine contraction, the playing of the model animation is accelerated, and in the descending period of uterine contraction, the playing of the model animation is made to be slower and slower, namely when k is less than 0, ID _ v is made to be smaller and smaller in the direction that k is smaller, when k is greater than 0, ID _ v is made to be larger and larger in the direction that k is larger and larger, and meanwhile, the influence of the size of the uterine pressure value m acquired immediately on the playing speed is considered, so that a model with the required animation playing speed is established: ID _ v _ 0+ α k + β m (shown in fig. 2); wherein, ID _ v represents the playing speed of the model animation when the uterus contracts; ID _ v0 represents the model animation normal play speed; k is expressed as the instantaneous slope of the uterine contraction curve; m represents a uterine pressure value; both alpha and beta are first controllable model parameters;
s20142, establishing an animation duration model, wherein the model is used for randomly selecting the required model animation duration by utilizing the duration of the contraction and the duration of the pause period;
specifically, for animation playing of each model in a scene, the animation playing should be continued until the uterine contraction period is ended, so that for the duration of the model animation, the selection or calculation should be preferably performed by referring to the last uterine contraction time and the pause period time, namely the uterine contraction time and the pause period time in the previous uterine contraction period, for the duration of the model animation; in the present embodiment (as shown in fig. 3), in order to enrich and diversify the animation effect, a model for obtaining the required animation duration is established in a random value manner: ID _ t ═ rand (ta, tb);
it can be seen that, for the required duration of the model animation, the specific calculation steps are as follows: randomly selecting a numerical value between two time length values of the previous contraction time length and the pause period time length as the required model animation duration time; that is, for the required model animation duration, it is the contraction duration ta from the previous contraction periodn-1And a rest period duration tbn-1Randomly selected between the two values;
s20143, establishing a scene model presenting quantity model, wherein the model is used for calculating the quantity of the scene models according to the uterine contraction curve instantaneous slope and the uterine pressure value;

s20144, establishing a scene animation speed model, wherein the model is used for calculating the scene animation speed when the uterine contraction occurs according to the normal speed of the scene animation, the instantaneous slope of the uterine contraction curve and the number of the calculated scene models;
specifically, let the scene animation speed be related to k and N, when k is larger, that is, when the uterine contraction is stronger, let the scene animation playing speed be faster, otherwise, let the scene animation playing speed be slower, however, in order to increase the coordination of the picture, the scene animation speed does not need to be faster in a lump when the scene models are more numerous, therefore, in this embodiment (as shown in fig. 5), the scene animation speed model to be constructed is specifically preferred: scene _ v ═ Scene _ v0+ epsilon k-theta/N; wherein Scene _ v represents Scene animation speed during uterine contraction; scene _ v0 represents the Scene animation normal speed; k is expressed as the instantaneous slope of the uterine contraction curve; n is expressed as the number of scene models; both ε and θ are the third controllable model parameters.
S202, the built model is utilized to realize multimedia music guide.
Specifically, the step S202 includes:
s2021, collecting uterine contraction data in real time;
s2022, calculating a driving parameter according to the collected uterine contraction data and a mapping model between the uterine contraction data and the feedback signal;
specifically, calculating the instantaneous slope k of a uterine contraction curve for uterine contraction data acquired in real time; wherein, the calculation formula of the uterine contraction curve instantaneous slope k is as follows:

since the uterine pressure can be transited from a stable state to a rising state when the uterine contraction period in the n-1 th uterine contraction period is transited to the uterine contraction period in the n-1 th uterine contraction period, during the period, when at least three uterine contraction curve instantaneous slopes k continuously calculated present a rising sequence, the k value is continuously calculated, when more than three k values continuously calculated form the rising sequence, the uterine contraction period can be considered to be started, the current moment is the moment of entering the uterine contraction, otherwise, the uterine contraction period is considered to be still in the intermittent period; similarly, the time of entering the intermittence period can be judged by calculating the uterine pressure value/the instantaneous slope k, so that the time of entering the intermittence period is judged;
in order to calculate the contraction time and the pause period time of each contraction cycle, the time of entering the contraction and the time of entering the pause period need to be recorded, that is, for the contraction time and the pause period time, their respective calculation formulas are as follows:
ta is intermittent (n) -uterine contraction (n)
tb as uterus contraction (n +1) -intermittence (n)
In the formula, ta is represented as the contraction duration in the nth contraction cycle; tb is expressed as the pause period duration in the nth uterine contraction period; pause (n) is expressed as the time when the nth uterine contraction period enters the pause period; the contraction (n) is expressed as the moment of entering the contraction in the nth contraction cycle; the contraction (n +1) is expressed as the time of entering the contraction in the n +1 th contraction cycle; that is, the uterine contraction duration of the current uterine contraction period is obtained by subtracting the uterine contraction entering time in the current uterine contraction period from the uterine contraction entering time in the current uterine contraction period, and the uterine contraction duration of the current uterine contraction period is obtained by subtracting the uterine contraction entering time in the current uterine contraction period from the uterine contraction entering time in the next uterine contraction period;
